1. Improved Cognitive Function: PhosSerine Complex contains phosphatidylserine, a type of fat that plays an important role in brain function. Research has shown that phosphatidylserine can improve memory, concentration, and overall cognitive function, making it beneficial for individuals with age-related cognitive decline or neurological disorders.
2. Reduced Stress and Anxiety: PhosSerine Complex has been found to have a calming effect on the brain, which may help reduce stress and anxiety. This is because phosphatidylserine can lower levels of cortisol, a hormone that is released during times of stress. By reducing cortisol levels, PhosSerine Complex may help improve overall mood and promote feelings of relaxation.

The Active Ingredient Is: Phosphatidylserine

Phosphatidylserine is a phospholipid (that makes up) part of cell membranes and (plays a part) in cell signalling (within) the brain. This form is (extracted) from sunflower lecithin using enzyme-assisted extraction and is suitable for vegetarians.

What Does Phosphatidylserine Do?

Phosphatidylserine is involved in cognitive activity, memory and learning, with research suggesting mood support too. This information lines up with EFSA and NHS guidance on normal brain function and phospholipid roles in neural processes.
